k Displaying the Location of an Error
If an error message (like “Math ERROR” or “Syntax ERROR”)
appears when you press =, press
d or e. This will display the
part of the calculation where the error occurred, with the cursor
positioned at the error location. You can then make necessary
corrections.
Example: When you input 14
ч 0 Ч 2 = by mistake instead of 14 ч
10
Ч 2 =
Use the insert mode for the following operation.
LINE
14/0*2=
Press e or d.
This is causing the error.
d1
=
You can also exit the error screen by pressing A, which clears the
calculation.
k Inputting with Math Format
When inputting with Math format, you can input and display fractions
and some functions using the same format as they appear in your
textbook.
Important!
• Certain types of expressions can cause the height of a calculation
formula to be greater than one display line. The maximum allowable
height of a calculation formula is two display screens (31 dots
× 2).
Further input will become impossible if the height of the calculation
you are inputting exceeds the allowable limit.
• Nesting of functions and parentheses is allowed. Further input will
become impossible if you nest too many functions and/or
parentheses. If this happens, divide the calculation into multiple
parts and calculate each part separately.
